Summary
Irvine requires every dog off its owner's property to be on a leash no longer than six feet and handled by a competent person. Sec. 4-5-701 bars letting a dog run at large on streets, sidewalks, trails, or someone else's property without consent, with narrow exceptions for approved off-leash dog parks and working dogs on duty.
Sec. 4-5-701. - Leash required. No person owning or having charge, care or custody of any dog shall cause, fail to curb, or allow the same to run at large upon any highway, street, alley, sidewalk, schoolyard, common area, trail, open space or other public place, or upon any private property or premises other than his or her own without written consent of the owner or leasee of such land, unless such dog is restrained by a substantial leash, not to exceed six feet in length, and in the charge of a person competent to restrain such dog. This section does not apply to an approved dog park where it is authorized to run your dog(s) off leash, nor does it apply to those situations enumerated under Section 4-5-707 of this chapter.

Full Breakdown
Sec. " The section carves out two exceptions: an approved dog park where off-leash play is authorized, and the working-dog situations in Sec. 4-5-707, which covers herding dogs under a handler's control and hunting, tracking, obedience, or show dogs actively performing. Sec. 4-5-705 separately confirms that a dog is not "at large" while running on its owner's own property, or on someone else's property with that owner's permission. Irvine's open space preserves apply a tighter, separate rule: Sec. 3-4-136 bars dogs from any open space area entirely, with the narrow exception of the Quail Hill Loop Trail if the Director of Community and Library Services opens it to dogs, and even then dogs must stay on a chain or leash no longer than six feet and remain on the designated trail.
Violations & Fines
Letting a dog run at large in violation of Sec. 4-5-701 is a misdemeanor under Sec. 4-5-1301, punishable as a separate offense for each day it continues, and an animal services officer or peace officer can impound the dog under the animal code's impoundment chapter. In City open space preserves, bringing a dog at all, outside an authorized opening of the Quail Hill Loop Trail, separately violates Sec. 3-4-136.
